Abstract
Disclosed is a method and apparatus for positioning and assembly of two or more parts wherein at least one of which is of a creep sensitive material. The method and apparatus enable very precise positioning of parts during assembly by holding a rough alignment with free play permitting finer alignment. Creep resistant annular inserts are molded into the part and provided with flow apertures to conduct plastic material into the annular insert bore. A spindle defined the geometry of a centering hole within the bore during molding. The annular inserts are operable as compression limiters to prevent deformation of the creep sensitive material under the action of heat or tightening stresses.
